5.  The applicants were born in 1932 and 1934, respectively, and live in Schalchen, Austria.
6.  The applicants run a fishing farm in Schalchen since 1976. Before that date the parents of the first applicant had run the fishing farm.
7.  Between 1956 and 1969 the Braunau River Engineering Directorate (Flussbauleitung) carried out regulation works on a small river in the vicinity of the applicants' estate without permission under the Water Act (Wasserrechtsgesetz 1959).
8.  In October 1969 the former owners of the estate requested the Braunau District Authority (Bezirkshauptmannschaft) to order the Municipalities of Mattighofen and Schalchen (“the Municipalities”) to re-establish the former state of the river bed maintaining that the regulation works had damaged the well which supplied their fishing farm with water. They submitted that the original capacity of the well had been 800 litres of water per second. After the regulation of the river the capacity of the well had been reduced to 100 litres of water per second. This constituted an interference with their water-rights. In case that the regulation could not be reversed they requested that the Municipalities be ordered to take other steps to ensure the water supply of the fishing farm.
9.  On 14 January 1970 the District Authority dismissed this request.

12.  On 3 September 1971 they filed again a request for transfer of jurisdiction and the Regional Governor again dismissed this request. The applicants' predecessors filed an appeal against this decision.

15.  On 23 August 1973 the Federal Minister dismissed the Municipalities' appeal.
16.  Subsequently, on 28 November 1973 the Municipalities applied for an ex post permission. On 3 June 1975 the District Authority held a hearing. At this hearing the applicants' predecessors requested that the Municipalities be ordered to pay compensation as they had suffered prejudice caused by the regulation works.
17.  On 3 September 1975 the District Authority granted the ex post permission and ordered the Municipalities to take specific steps to ensure the water supply of the fishing farm before 31 December 1976. The District Authority dismissed the request for compensation.
18.  On 2 December 1975 Regional Governor dismissed the applicants' predecessors' appeal and found that their water rights were not violated by the granted permission.
19.   On 27 January 1976 the Federal Minister rejected the applicants' predecessors' appeal as belated. Subsequently, they lodged a request for leave to appeal out of time (Wiedereinsetzung in den vorigen Stand).

25.  On 28 May 1982 the District Authority granted once more the ex post permission for the regulation works and dismissed the applicants' request for compensation.
26.  On 28 June 1982 the applicants filed an appeal against this decision. In the years to follow several technical experts were appointed in order to establish whether the regulation works had damaged the well.
27.  On 11 November 1984, as the District Authority had not taken a decision, the Municipalities filed an application for transfer of jurisdiction (Devolutionsantrag) with the Regional Governor.
